Also called the Twin Witches, they were two powerful women wizards;
Herin was specialized in White Magic,
while her sister Urdin was a master of the Black Art.
Both of them tried to improve the life of the people living all around their house,
and introduced the use of cats as spirit-watchers in Scorn.
Unfortunately for them, they were burned by an angry Brestian fanatical mob
for “illegal use of Arcane Powers”.
